当部分に穴を設けずに盲にすることで封止する試
みが行われている。 As is well known, cylinder blocks and cylinder heads are designed with a certain degree of versatility so that they can be used in engines with different specifications. For this reason, the holes may also be unnecessary depending on the specifications of the engine. Therefore,
In such a case, it is necessary to seal the holes opened in the mounting surfaces of both members. If this hole is sealed with a cover or something similar, the number of parts and work hours will increase, so it is not necessary to provide a hole in the corresponding part of the gasket interposed between the cylinder block and cylinder head. Attempts are being made to block this by blinding people.
このようにガスケツトによつて封止する場合に

The sealing means when using a metal gasket as the gasket to blind the above-mentioned open hole is as follows:
It is most industrially preferable to use beads. However, in order to effectively seal with beads and to facilitate manufacturing, it is generally necessary to set the thickness of the metal plate to, for example, about 0.2 to 0.3 mm.

険がある。 Therefore, when sealing a hole that has pressure, such as engine cooling water or lubricating oil, if a hole is similarly opened on the cylinder head side at a position corresponding to the hole position, the above-mentioned The pressure may cause a deformation in which the blind metal plate is pushed out so that it bulges out to the opposite side. Generally, this deformation affects the sealing performance, and during long-term use, fluid may leak to the outside, which may shorten the overall lifespan.

ある。 Further, the third configuration of the metal laminated gasket with a blind portion of the present invention is that a bead plate that surrounds the hole to be sealed is provided with a bead that surrounds the hole to be sealed on one side of the bead plate. On one side of the bead plate, a step portion recessed in the shape of a flat-bottom dish is provided on the outside of the hole to be sealed, and a first blind plate provided with a recess portion that blinds the hole is arranged, and on the other side. A second blind plate is arranged in which the hole is formed into a flat plate shape and provided with a bead for sealing the hole, and the metal plate disposed between the first and second blind plates has the recessed part. The blind portion is provided with a through hole through which the recess is inserted, and the depth of the recessed portion is equal to or less than the distance between the first blind plate and the second blind plate when no load is applied.

しないように形成することがより好ましい。 The cross-sectional shape of the dish-shaped recess usually has a stepped edge and a mostly flat bottom, but is not limited to this and can have other shapes. . Further, the recessed portion does not prevent the recessed portion from being in contact with the other blind plate when no tightening force is applied, but in consideration of manufacturing accuracy, it is more preferable to form the recessed portion so that the recessed portion does not come into contact with the other blind plate.
前記くぼみ部は、金属薄板から成る盲板の強度

用する。 A configuration in which the depth of the recessed portion is set such that the two blind plates of the above configuration contact each other without applying a tightening load to the metal laminated gasket of the present invention, or contact each other when a tightening load is applied, is as follows: By applying a tightening load, the sealing action of the bead is effectively exerted without being affected by the recessed part, and by laminating the first and second blind plates in the recessed part, the strength of the thin metal plate is increased. It acts to withstand the fluid pressure that acts on the blind area.
また前記第１及び第２盲板の間には、複数の板
を介在させて窪み深さをより大きくして、くぼみ
部周囲の段差部によるシール作用をより強く発揮
させるようにすることもできる。 Further, a plurality of plates may be interposed between the first and second blind plates to further increase the depth of the depression, so that the sealing effect of the stepped portion around the depression can be more strongly exerted.
